ajouter imageview dynamiquement à vue

je suis prise de jeu android qui utilisent la classe view.je ne suis pas à l'aide de mise en page.toutes mes images est un dessin avec de la toile.Maintenant mon problème est que je ne peut pas donner une image bitmap

palpable événement comme vous le savez.je suis en train d'ajouter imageview de façon dynamique pour ma classe de vue

utilisation tactile de l'événement.pourquoi j'essaie d'ajouter imageview dynamiquement?Parce que je ne suis pas à l'aide de

mise en page.mais je ne pouvais pas.est-il un corps?

here is my code:
